Hi,
Nice to meet ya! Yes, we all seem to have had the same struggle in our youth, finding a opponent wasnt easy. Luckily online there are many players, from all over the world. I am from the Netherlands.
Well its important to have TripleA installed, you can find it online: https://triplea-game.org/download/
Perhaps there are some new versions of it, so always check with your opponent which version he is using, otherwise you are probably not compatible.
You can play trough PBEM (which stands for Play By Email) or online (large community) or trough the forum (this site). You can also play vs a AI, its nice to play against, but its not that developed yet. But for training purpose it will do, in order to learn a map you havent played much yet.
Well good luck and have fun playing! Hope youll enjoy it and have fun!
